I just got my new MacBook Pro with Retina Display and I am noticing an odd noise. It is a high-pitched hum and it happens when scrolling on webpages or installing software. It also has some weird clicking noise. I don't understand this because the new MacBook Pro is flash storage and has no moving parts other than the fan. This is definitely not the fan. I called AppleCare and they told me to reset PRAM and NVRAM and reset the SMC. This did not fix the problem. Then, they told me to reinstall Lion. I did that, and that didn't work either. They told me they would call me back to set up a 'capture'. Hopefully they will just give me a new machine because this is 15 days old. Is anyone else having this problem? (Thank god I have AppleCare) Thanks.
